Definitions

the present invention relates to the taking of heavy loads, with a view to their handling, and more particularly to the lateral taking of such loads.
Lifting rings are known which are calculated and produced for the vertical taking of heavy loads, that is to say lifting rings which are fixed in a vertical orientation in the part to be lifted. It happens that, for convenience, some users use these known lifting rings by fixing them laterally, that is to say along a horizontal fixing axis, on heavy loads whose manipulation involves turning operations such as for example that fillers formed by certain molds. The stresses to which the lifting ring is then subjected in this type of handling being of a different nature from those which the latter is designed to withstand, the risk is then great that a rupture of the ring occurs during handling by being able to cause serious accidents.
Such known lifting rings are for example described in documents US-A-4074519, US-A-4705422, US-A-3905633 and DE-A-3435961.
the object of the present invention is to remedy this drawback of conventional lifting rings and to this end it proposes an improved lifting ring allowing, in complete safety, the lateral grip and the handling of heavy loads.
the lifting ring is constituted by a monobloc assembly made of high strength steel, and it comprises a body having a threaded part continuing with a support part of larger diameter on which a piece comes to bear. intermediate in the form of a crown, of height less than that of the support part and designed to rotate 360 ° around this support part and to serve as a pivot axis, also 360 °, for a hooking loop.
the support part of the body of the hooking ring continues with a head part which serves as a stop for the intermediate piece and which has in its central part a hollow actuation part for the introduction of a key. Clamping.
the fixing by screwing of the hooking ring in the load to be handled causes the blocking of the ring body in the bottom of the load housing, the threaded part of the body as well as a certain length of the support part intermediate thereof being engaged in the housing of the load, however providing the necessary operating clearance between the load and the end of the branches of the hooking loop. It is understood that, when handling the part by means of a lifting system cooperating with the hooking loop, the lifting ring provides a resistance allowing, in the case of two lifting rings aligned on both sides of load, safely reach maximum usage loads of more than 20 tonnes (in the case of M56).
the two hooking rings being thus arranged in alignment on both sides of the load, to form an axis of rotation, it is understood that one can then obtain the reversal of the load.
the lifting ring comprises a body of high strength steel having a threaded portion 1 of large diameter which continues with a support portion 2 of a slightly larger diameter , then by a head portion 3 of an even larger diameter.
This head part 3 has at its central part an imprint 4 in the form of a hexagon socket for the engagement of a standard tightening key (not shown in the drawing).
a part 5 in the form of a crown of length less than that of the support part and having on its entire periphery an internal groove 6 intended, when the part 5 is in abutment against the part of head 3, coming opposite a peripheral groove 7 on the outer face of the support part 2.
the support part 2 has two projecting axes 9 projecting radially and in the extension of one another, which respectively serve as trunnions for openings 10 facing the two branches of a hooking loop. 11. Said loop 11 can therefore freely rotate 360 ° around the pins 9, this possibility of rotation being however limited to approximately 180 °, as seen in FIG. 2, when the lifting ring is fixed laterally to a load 12.
the positioning of the lifting ring on the load 12 is carried out by screwing, by means of a key inserted into the hollow 4 of the head part 3, until the threaded part 1 comes to lock at the bottom of the housing 13 provided in the load 12. In this position a certain part of the length of the support piece (2) is also engaged inside the housing 13 by providing an effective power take-off.
lifting rings according to the invention when two lifting rings according to the invention have thus been arranged laterally on the load 12, one opposite the other to form an axis of rotation, it is possible to easily turn the load through to the possibility of rotation of the part 5 on the support part 2.
the lifting ring according to the invention can of course also be used for ordinary lifting operations, that is to say with screwing axis vertical.
d denotes the diameter of the threaded part 1
D denotes the diameter of the support part 2
L is the minimum length of the tapped part 1
l is the length of the support part 2 centered in the housing of the load
C1 represents the maximum working load in the case of two fixing lifting rings horizontal
C2 represents the maximum working load in the case of a single lifting ring with vertical fixing.
